The graphite grounding wire is in the shape of a cable and is made of high carbon graphite and other materials through advanced production processes. Belonging to non-metallic conductive materials, it is corrosion-resistant, rust resistant, does not resist high current impact, resistant to high and low temperatures, has stable grounding resistance, is maintenance free, update free, safe and reliable.
It has the following main performance characteristics
1. Good conductivity and impulse current tolerance characteristics.
2. Reliable corrosion resistance.
3. Mechanical structure stability.
4. Good thermal stability.
5. Convenient transportation and construction, with high adhesion to the soil.
6. Prevent theft and human sabotage.
Compared with other traditional grounding electrodes, the use of soft graphite grounding electrodes in combination with soft graphite grounding modules reduces electrical resistivity and outperforms other traditional grounding electrodes. It saves 50% of excavation volume, reduces construction intensity, shortens construction time, and reduces costs by 50%. It has a service life of over 50 years and no secondary maintenance costs. In mountainous areas with inconvenient transportation, there is no need to transport bulky equipment such as welding machines. The installation process is simplified and can be connected by lap joints, greatly shortening the installation and construction time. Overall, it has high cost-effectiveness and significant advantages in all aspects. Therefore, soft graphite grounding electrodes are a good choice in high soil resistivity grounding projects.
Graphite grounding wire has been widely used in the lightning protection and grounding industry due to its strong advantages, but with it comes the issue of product quality assurance. Nowadays, there are many counterfeit products on the market, and how to distinguish between good and bad has become a top priority.
Flexible graphite grounding wire is made by processing expanded graphite with various reinforcing materials such as fibers and metal wires, and adding adhesives.
Expanded graphite packing, also known as flexible graphite packing, is made by weaving flexible graphite wire through the core and woven with glass fiber reinforced graphite wire to reduce the loss on ignition of the product. Expanded graphite packing has good self-lubricating and thermal conductivity, low friction coefficient, strong versatility, good flexibility, and high strength.
To determine which type of packing is good, one should choose based on the working conditions. The quality of the packing should be judged by its appearance and strength. Check if the appearance color is smooth. High quality graphite packing has a black and bright color, and check if there are graphite chips falling off when gently bent by hand. Poor quality graphite packing will have graphite chips falling off. Graphite packing should mainly depend on the carbon content of graphite and the metal wires added inside. Graphite with good carbon content is generally above 98%, while metal wires with good carbon content are those with nickel wires added. These cannot be seen from the surface and generally require laboratory testing.
Legitimate products are processed through special techniques, exhibiting inertness, excellent chemical properties, corrosion resistance, and high temperature resistance. They are suitable for special soil environments such as acidic and alkaline soils. Imitation products only use the purchased packing directly or change its appearance before use. The product has unstable performance and is prone to safety hazards such as ground potential counterattack. After being buried for a period of time, it will corrode and break, making it completely unsuitable for lightning protection and grounding. The above is the introduction of the graphite grounding editor.
